Embodiment

[0015] Example: such as figure 1 As shown, a dimming LED lamp circuit with an electronically controlled dimming transparent plate, including an electronically controlled dimming transparent plate, a resistance-capacitance step-down circuit, a voltage regulation circuit, a signal receiving circuit, a state control circuit, and a voltage stabilizing circuit , an optocoupler T, a constant current conversion circuit, a rectifier circuit and an LED lighting circuit; Light-transmitting and transparent state, and its transparency corresponds to the magnitude of the AC voltage loaded between the first terminal and the second terminal. Negative output terminal, when the live wire connection terminal and the neutral line connection terminal of the resistance-capacitance step-down circuit are connected to the AC voltage of the mains, the AC voltage is output between the AC output terminal and the neutral line connection terminal, and at the same time, the positive output terminal and the...

Abstract

The invention discloses a dimming LED lamp circuit with an electric control dimming light-transmitting plate, which comprises the electric control dimming light-transmitting plate, a resistance-capacitance voltage reduction circuit, a voltage regulation circuit, a signal receiving circuit, a state control circuit, a voltage stabilizing circuit, an optical coupler, a constant current conversion circuit, a rectifying circuit and an LED light-emitting circuit. During lightness adjustment, the state control circuit outputs corresponding electric signals at the brightness control end of the state control circuit to control the optocoupler to form corresponding PWM signal output, the constant-current conversion circuit outputs direct currents with corresponding magnitudes between the positive output end and the negative output end of the constant-current conversion circuit after receiving the PWM signals, the LED light-emitting circuit emits light with corresponding brightness, and when transparency is adjusted, the state control circuit outputs a corresponding electric signal at the transparency control end of the state control circuit, changes the voltage between the alternating current output end and the zero line connecting end of the resistance-capacitance voltage reduction circuit, and adjusts the transparency of the electric control dimming light-transmitting plate; and the dimming LED lamp circuit has the advantage that the functions of light-transmitting illumination and floodlight illumination can be simultaneously realized.

Description

technical field [0001] The invention relates to a dimming LED lamp circuit, in particular to a dimming LED lamp circuit with an electronically controlled dimming light-transmitting plate. Background technique [0002] Existing dimming LED lamps usually have a light-transmitting component (transparent plate or light-transmitting cover), the light-transmitting component has an incident surface and a light-emitting surface, and the incident surface of the light-transmitting component is facing the light-emitting surface of the LED light source board inside the LED lamp After installation, the light emitted by the illuminant on the light-emitting surface of the LED light source board is incident from the incident surface of the light-transmitting component, passes through the light-transmitting component, and then exits from the light-emitting surface of the light-transmitting plate. According to different requirements of dimmable LED lights, the light-transmitting parts have li...
